To all whom-fit may concern:

Be it known that I, CHARLES HARRISON 'W1LsoN,- a citizen of the United States, and

resident of Red Oak, in the county of Montgomery and State of Iowa, have invented an Improvement in Construction of Buildplastic blocks,

lin of which the followin is a specification.

invention is an improvement in concrete structures, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawing forming a part hereof, Fi ure 1 is a perspective view of the facing of tIie building constructed in accordance with my improvement. Fig. 2 is a ver tical section through a part of the` wall. Fig. 3 isga detail perspective view of a part of the reinforce. Fig. 4 is a detail of one of the ties; and Fig. 5 is a vertical section through a portion of the wall on the line of the tie.

M improved structure consists of a llinef .of plastic material and a facing ofl molde each of the blocks containing a reinforce comprising horizontal and vertical bars, and each of said bars is provided at one end with a pair of ears and at the other with a lug adapted to be received between the ears of a bar in the adjacent block, the lu s and the ears being connected together in suc manner as to form a plurality of continuous vertical reinforces and a plurality of horizontal reinforces in the facing, the facing being suitably tied to the filling.

Each of the blocks A is of suitable shapeand size, and is provided with a horizontal reinforcing bar a, and a plurality of vertical reinforcing bars a', each of said reinforces consisting of a bar rectangular in cross section and provided at one end with a pair of ears a3 and the other end c projects beyond the block, the horizontal and the vertical ars being connected together byl rivets a5.

The reinforcing bars are placed in the block when it is molded, and are so arranged that tl e ends of the ears a,3 areiiush with the face othe block, while the end a* rejects therebeyond. Both the ears and t e projectin ends are provided with openings a theret rough, the opening in the projecting` ends being sol arranged as to aline with the openings 1n the ears, when the ends are inserted therebetween, and ins a7 are adapted to be inserted through t e alined openings to bind the adjacent blocks together.

next `upper block.

` At the corners of the structure, the horizontal reinforcing bars are` bent as at a8, the bend correspondingto the shape of the structure. That is, in ciicular structures the bend would be a curve, while in rectangular structures, the bend would be a right anffle.

In constructing the structure, the blocks are laid in courses, and to place the last block in each course, lit is necessary to provide a vertical groove a in the end of the said last block for receiving the lug a4 of the adjacent block and to provide another groove a in the block to whose horizontal 'reinforce the horizontal reinforce of the last block will be connected. The grooves a, are in vertical alinement with the opening between the ears of the horizontal reinforce so that the last block may slip downward on tothe blocks of the receding course.

Tfie last block referred to above, is intended to mean the last block which is ut in lace, regardless of the position o' such lilock in the course.

In molding the blocks, the reinforces are properly placed in the mold, with suitable pins inserted through the openings of the ears, after which the plastic material is tam ed in the mold. After the plastic materia set, the pins are driven out and the block is ready for use.

vThe facing isltied to the. filling B by a tie D, of the shape shown in Fig. 4, the said tie comprising a plate having one of its ends split longltudinally as at d, the material on each side ofthe split being turned in o posite directions to form a cross bar d', an the opposite end d2 of the plate is bent at a right angle to the lplate to overlap the horizontal reinforce a. The vties are placed with the angular portion cl2 abutting against an ear a3, and the said ties may be placed one at every joint, or in any desired arrangement. It will be noticed that the ties are placed with their widest dimension perpendicular to the reinforce, and they are arranged between the abutting ends of the blocks.

I claim:

1. A structure comprising a filling of plasf end a pair oi` ears,

the ears *Flush `with the face of the 1mock, the

block being recessed between the ears,l said ears and the projecting ends being provided with alined openings, a pin traversing the openings for securing the parts together, whereby to Aforni a pluralitv of continuous vertical reinforces and a plurality of horizontal reinforces, said horizontalreintorces being bent at the corners'oi the structure, snndr)T of said blocks in' eech course being provided ivith'vertical grooves in their ends for the purpose set forth, and plurality of ties ior connecting the liacing'with the filling, said ties coniprisingeach afplate having-one of its ends split, the portions of the plate on each side of the split being bent in opposite directions, the other end oi the tie being bent at a right angle to the remainder thereof and overlapping the horizontal reinforcej '2. A. structure comprising a filling of plastic material, and facing of molded plastic blocks, each of said blocks containing a reinforce comprising connected horizontal and vertical bars, each of said bars having at one end a pair orc ears, and at thelother projectbetween the ears eeaeee ing beyond the block and adapted to be received between the ears of a bar in an adjacent block, said bars being arranged With the ears :dushwith theface of the block., theblock being recessed between the ears, said ears and the projecting ends being provided With alined openings, a pin traversing the openings for securinglr the parts together, whereby to form a pluraiity oiC continuous vertical reinforces and a plurality of horizontal reinforces, said horizontal reinforces ners of the structure, sundry of said blocks in each course being provided with vertical grooves in their ends for the purpose set forth, and a plurality of ties for connecting the facing with the lling. v

3. A structure comprising a filling of plastic material, andi a facing of molded plastic blocks, each of said blocks containing a reintorce comprising connected horizontal and vertical bars, each of said bars having at one end a pair of ears and at the other projectin beyond the block and adapted to be received of the bar 'of an adjacent block, the bloei. being recessed-between the earsbsaid ears and progecting ends being provided with alined openings, pins traversing the openings for securing the parts together, and nieans for CHARLIE?, HARRSON WILSON 1l(/litnesses:
